It's the last days of summer. Best friends Seth and Jameson are getting ready to perform-and party-at local rock venue The Alamo. But before the night begins, both young men come face- to-face with serious reality checks: Seth receives life-changing news from his girlfriend Mel, and Jameson has to choose between his on-again-off-again girlfriend Corin and a new girl he's just met, the outspoken Harmony. At the show, Seth and Jameson's friends are too caught up in their own lives to be much help: young rocker Taylor romances his new crush Dana, and awkward Jack "Rabbit" avoids his childhood friend Lexi after learning what she did at her sister's wedding. These intertwining friend-dramas, fueled by a lot of drinking, unfold against a backdrop of live music performed by the best bands in town. By the end of the night, these young men and women are confronted with a series of fast- approaching life decisions that will either leave them stuck in the comfort of adolescence, or catapult them into adulthood.
